It may be that no ET species is perfect, completely benign and honorable. Just like human beings. But your descriptions of "rude, deceptive, and egocentric" beings and "Narcissistic, authoritarian personalities" is also a good way of characterizing humans and the god of the Bible, the gods of ancient Greece, the gods of the Aztecs, the gods of the Hindus, and the gods of every culture on earth. "As below, so above", and vice versa.
It's all very entertaining.
